【正文】 摘 要近年來全國各地的霧霾問題日漸嚴(yán)重，粗獷經(jīng)濟(jì)發(fā)展模式在我國已經(jīng)行不通。新能源、可再生能源開發(fā)利用和節(jié)能減排是我國基本國策。熱泵是能夠?qū)⒌推肺粺崮苻D(zhuǎn)換為高品味熱能的裝置，從而實(shí)現(xiàn)工業(yè)廢熱的再利用，不僅節(jié)能更可以提高能源的利用率，所以熱泵裝置的開發(fā)利用，符合我國目前經(jīng)濟(jì)發(fā)展?fàn)顩r和環(huán)境狀況。熱泵分類中水源蒸汽壓縮式熱泵是比較常用的形式，具有熱源分布廣，結(jié)構(gòu)簡單，初投資少，不污染水源等特點(diǎn)。本文主要進(jìn)行煉鋼廠冷卻水水源熱泵的設(shè)計(jì)，經(jīng)過分析國內(nèi)外實(shí)例及經(jīng)濟(jì)性分析比較后，最后確定了開啟式單螺桿熱泵機(jī)組的研究方案，并在熱源提取上進(jìn)行創(chuàng)新，解決了煉鋼廠冷卻水降溫后結(jié)渣堵塞換熱器的難題。所以此方案兼具可靠性和經(jīng)濟(jì)性。本設(shè)計(jì)先對系統(tǒng)工作原理進(jìn)行闡述，并進(jìn)行方案論證。確定方案后進(jìn)行系統(tǒng)的熱力計(jì)算，由熱力計(jì)算的結(jié)果對系統(tǒng)蒸發(fā)器和冷凝器進(jìn)行設(shè)計(jì)計(jì)算，并得出所需壓縮機(jī)的參數(shù)，然后進(jìn)行壓縮機(jī)選型。最后還對系統(tǒng)的其他零部件進(jìn)行選型，其中包括真空泵，軸流風(fēng)機(jī)，膨脹閥及油過濾器。最后還完成了系統(tǒng)流程圖，蒸發(fā)器，冷凝器以及中間換熱器的裝備圖。關(guān)鍵詞： 熱泵機(jī)組；冷凝器； 蒸發(fā)器AbstractIn recent years, haze increasingly serious problem across the country, the rough model of economic development in China has not feasible. New energy, renewable energy development and utilization and energy conservation is China39。s basic national policy. Heat pumps are able to convert lowgrade heat energy means high taste, enabling reuse of industrial waste, not only energy but also improve energy efficiency, so the development of a heat pump unit, in line with the current economic development and environmental conditions in China. Classification of water vapor pression heat pump heat pump is a relatively mon form, has a wide heat distribution, simple structure, low initial investment, do not pollute the water and so on. This paper mainly steel plant cooling water source heat pump design, through analysis of examples and parative economic analysis of the domestic and foreign, the finalization of the opentype single screw pump units research programs and innovation in the heat extraction to solve the steel after cooling plant cooling water heat exchanger clogging slagging problems. So this program both reliability and economy. After determining program of thermodynamic calculation system, the results calculated by the heat of the system evaporator and condenser design calculations and draw the required parameters of the pressor, then the pressor selection. Finally, other parts of the system for selection, including vacuum pumps, axial fan, expansion valve and oil filter. Finally, to plete the system flow chart, an evaporator, a condenser and an intermediate heat exchanger equipment Fig.Keyword: heat pump, condenser, evaporator目 錄摘 要 ................................................................................................................................IABSTRACT ....................................................................................................................II目 錄 ..............................................................................................................................III第 1 章 緒論 .............................................................................................................. 1 課題背景 ............................................................................................................ 1 國內(nèi)外在該方向上的研究現(xiàn)狀及分析 ............................................................ 2 主要研究內(nèi)容 ............................................................................................ 2 本設(shè)計(jì)主要完成的內(nèi)容 ............................................................................. 3 熱泵技術(shù)在國內(nèi)外的發(fā)展 ................................................................................. 3 設(shè)計(jì)原理概述 ..................................................................................................... 4 系統(tǒng)設(shè)計(jì)方案選擇 ............................................................................................. 5 方案論證 .................................................................................................... 6 熱泵機(jī)組壓縮機(jī)型式的選擇 .................................................................... 7 潤滑系統(tǒng)比較 ............................................................................................ 8 熱源側(cè)放熱方式的選擇 .......................................................................... 8 本章小結(jié) ............................................................................................................ 8 第 2 章 系統(tǒng)的熱力計(jì)算及壓縮機(jī)選型 .................................................................. 9 給定條件 ............................................................................................................ 9 熱力計(jì)算所對應(yīng)的壓焓圖以及參數(shù)列表 ........................................................ 9 熱力計(jì)算過程 ................................................................................................. 10 壓縮機(jī)概述 ....................................................................................................... 11 容積式壓縮機(jī)的特性和主要生產(chǎn)廠家 .......................................................... 11 往復(fù)活塞式 .............................................................................................. 11 回轉(zhuǎn)式 ....................................................................................................... 12 壓縮機(jī)的型式確定 .................................................................................. 12 螺桿壓縮機(jī)的選型計(jì)算 ................................................................................. 13 本章小結(jié) .......................................................................................................... 14 第 3 章 冷凝器的設(shè)計(jì)計(jì)算 .................................................................................. 16 冷凝器的型式和結(jié)構(gòu) ....................................................................................... 16 空氣冷卻式冷凝器 .................................................................................. 16 水冷式冷凝器 .......................................................................................... 16 冷凝器選型 .............................................................................................. 18 冷凝器設(shè)計(jì)計(jì)算 .............................................................................................. 18 冷凝器的技術(shù)參數(shù) .................................................................................. 18 冷凝器設(shè)計(jì)計(jì)算過程 ............................................................................ 18 冷凝器傳
